instrument lighting problems

My Park/Tail lights fuse kept blowing out. I couldn't figure it out. At around the same time my left tail light went (whether this has any significance or not im not sure) I had no fuses except a 30, (it takes a 25 I believe) I put it in and turned the park lights on, and then my dash almost instantly started smoking. Turned it off and pulled the fuse. It was hot but didn't blow. Now I put a 20 amp fuse in and the park and tail lights work but none of my interior instruments light up. Where is my problem coming from. I installed a new horn at the same time. Is this on the same circut??

Re: instrument lighting problems

It seems the problem exists in the dash lamp mylar circuitry panel... or something connected to it. Try taking ALL the dash lamps out and turning on the dash light switch. If the fuse blows, it's a problem in the switch, in the wiring to the panel, or in the panel itself. Let me know...

Geez'e Guys... don't any one out there have a YJ schematic they could email me? I'm beggin' here!

Re: instrument lighting problems

Ok.. this is an assumption... as I don't have a YJ schematic..I'm just guessin' here 'cuz no one else is responding...

Look at the headlight switch... Does it have an instrument panle dimmer built in? If so, the dimmer could be bad, the wiper dirty, or the the switch is bad.

I would find the voltage feed wire to the instruments and see if half the instrument lamps could be unhookded from the feed wire. Then try the lamps. If everything is normal... you know the problem is in the half that are not connected. If the fues again blows, you know that the problem is in the half of the fuses that are still connected.

Now the problem could be in the harness itself, or a connector. A these lamps and guages are aftermarket, I'd vote for a bad connector on one of the gauges that's brushing up against gauge mount and blowing the fuse.
